原发性腹膜后肿瘤的诊断与治疗

目的：总结原发性腹膜后肿瘤（PRT）的诊断方法和手术经验。方法：回顾性分析2007年5月至2009年4月38例经手术治疗的PRT患者,总结分析其影像学特点、病理学类型、手术治疗及随访结果。结果：良性肿瘤11例,恶性肿瘤27例,均经病理证实为PRT。肿瘤完整切除36例,姑息性切除1例,细针穿刺活检1例;合并脏器切除及血管切除重建11例;复发9例,复发后完整切除8例,姑息性切除1例。随访时间为20～43个月,11例良性肿瘤患者的1、3年生存率分别为100%和90.9%。24例恶性肿瘤患者的1、3年生存率分别为66.7%和33.3%。结论：影像学检查对PRT术前诊断和手术方式的选择具有指导意义,完整切除肿瘤,必要时合并脏器切除及血管切除重建时治疗本病的最有效的方法。

Diagnosis and treatment of primary retroperitoneal tumor

Objective： To summarize the experience in diagnosis and surgical treatment of primary retroperitoneal tumor（PRT）.Methods： Clinical data of 38 PRT patients from March 2007 to April 2009 were retrospectively analyzed including image examination,pathologic examination,surgical treatment and follow-up.Results： Tumors were benign in 11 patients and malignant in 27 patients,all of that were diagnosised by pathologic examination.Of the 38 patients,36 underwent complete resection,1 uncomplete resection and 1 fine needle aspiration.11 patients underwent adjacent organ resection and vessel reestablishment.There were 9 recurrent PRT patients,8 of them underwent complete resection,1 underwent uncomplete resection.The time of follow-up were 20 to 43 months,the one-year and three-year survival rate of 11 benign PRT were 100% and 90.9% respectively.The one-year and three-year survival rate of 24 malignant PRT were 66.7% and 33.3% respectively.Conclusion： Preoperative image examination is crucial for diagnosis and operative modus.The most effective treatment of PRT is complete resection,an adjacent organ resection and vessel reestablishment if necessary.
